The California collaborative network to promote data driven care and improve outcomes in early psychosis (EPI-CAL) project: rationale, background, design and methodology.

A prolonged first episode of psychosis (FEP) without adequate treatment is a predictor of poor clinical, functional, and health outcomes and significant economic burden. Team-based "coordinated specialty care" (CSC) for early psychosis (EP) has established effectiveness in promoting clinical and functional recovery. However, California's CSC program implementation has been unsystematic and could benefit from standardizing its processes and data collection infrastructure. To address this, we established a consortium of EP clinics across the state via a Learning Health Care Network (LHCN) framework to develop the Early Psychosis Intervention Network of California (EPI-CAL). EPI-CAL's LHCN developed a core battery of evidence-based measures for service users and family members and linked them together using a unique data collection and visualization application, Beehive. EPI-CAL's LHCN collects, visualizes, and aggregates data at the individual and clinic level for EP programs across California via Beehive. Beehive was designed to: (1) collect outcomes data from service users receiving care at EP programs and their support persons, (2) provide the data to providers on a secure web-based dashboard to support measurement-based care, and (3) allow data to be used for program or research analysis. We will (1) determine the feasibility of implementing an LHCN across a diverse, decentralized network of early psychosis programs, (2) determine if the implementation of an LHCN increases the delivery of measurement-based care, and (3) determine if the implementation of measurement-based care is associated with significant improvements in key service user outcomes. EPI-CAL's network will contribute data to the Early Psychosis Intervention Network (EPINET) program. The current study aims to establish an LHCN of EP clinics in California that implements harmonized data collection using Beehive and assesses the feasibility of establishing such a network. Our goal is for this harmonized data collection approach to be used to inform decisions and develop learning opportunities for service users, staff, and administrators, and to improve outcomes for service users and their supporters in CSC care. Further, the data will enable programs and research teams to examine what elements of care lead to program success and improved treatment outcomes for service users. www. gov , identifier NCT04007510; registered 07/05/2019.

Enhancing reef carbonate budgets through coral restoration.

Complex reef structure, built via calcium carbonate production by stony corals and other calcifying taxa, supports key ecosystem services. However, the decline in coral cover on reefs of the Florida Reef Tract (US), caused by ocean warming, disease, and other stressors, has led to erosion exceeding accretion, causing net loss of reef framework. Active coral restoration, aimed at rapidly increasing coral cover, is essential for recovering reef structure and function. Traditionally, restoration success focused on the survivorship and growth of transplanted corals. This is the first empirical study to examine the role of high-density outplants of the endangered staghorn coral, Acropora cervicornis, in restoring positive carbonate accretion on Florida reefs. Successful transplantation of staghorn corals contributed to positive net carbonate production. Restored plots yielded a mean net carbonate production rate of 3.06kg CaCO3 m- 2 yr- 1, whereas control plots exhibited net erosive states. Staghorn restoration plots sustained positive net carbonate production at a threshold of ~ 2.96% coral cover. However, bleaching, storms, and disease challenge these reefs, highlighting the need for restoration strategies that enhance resilience to environmental stressors. Establishing Acroporid aggregations through outplanting, alongside climate adaptation strategies, could foster reef habitat growth and enhance the recovery of ecosystem services.

Bridging the digital divide: mapping Internet connectivity evolution, inequalities, and resilience in six Brazilian cities

We investigate the evolution of Internet speed and its implications for access to key digital services, as well as the resilience of the network during crises, focusing on six major Brazilian cities: Belo Horizonte, Brasília, Fortaleza, Manaus, Rio de Janeiro, and São Paulo. Leveraging a unique dataset of Internet Speedtest® results provided by Ookla®, we analyze Internet speed trends from 2017 to 2023. Our findings reveal significant improvements in Internet speed across all cities. However, we find that prosperous areas generally exhibit better Internet access, and that the dependence of Internet quality on wealth have increased over time. Additionally, we investigate the impact of Internet quality on access to critical online services, focusing on e-learning. Our analysis shows that nearly 13% of catchment areas around educational facilities have Internet speeds below the threshold required for e-learning, with disadvantaged areas experiencing more significant challenges. Moreover, we investigate the network’s resilience during the COVID-19 pandemic, finding a sharp decline in network quality following the declaration of national emergency. We also find that less wealthy areas experience larger drops in network quality during crises. Overall, this study underscores the importance of addressing disparities in Internet access to ensure equitable digital services and enhance network resilience during crises.

Migration, Urbanism and Health: Moving Toward Systems-Informed Policy and Practice

Migration and displacement are pivotal determinants of urban health, influencing both direct and indirect health outcomes. Migrants may face unique health risks, often exacerbated by economic, social, and environmental factors encountered during transit or upon resettlement. As migration patterns shift due to geopolitical, climatic, and economic pressures, they reshape the global and urban policy landscapes in unpredictable ways, presenting challenges that will continue to evolve in the coming decades. Current legal frameworks, in many cases, do not adequately account for migrant populations, hindering policy responses and complicating the protection of migrant health. Therefore, effective urban health interventions must be inclusive of migrant populations and expand beyond healthcare services. A systems-thinking approach that recognizes the broader determinants of health—including housing, employment, social services, and urban infrastructure—is essential to address the intersecting challenges migrants face. Despite these challenges, migration remains crucial to the functioning of urban environments. Migrant workers consistently contribute to the healthy operation of cities, underpinning key infrastructure and services. However, to optimize policy responses and improve urban health outcomes, more robust data and evidence on the health risks and outcomes of migrants, as well as the structural drivers of migration, are needed. Moreover, macro factors such as climate change, future pandemics, and geopolitical shifts are likely to influence both migration dynamics and migrant health. To anticipate and respond to these evolving challenges, a systems-informed and holistic vision of urban health is required—one that integrates migration into the broader urban policy and planning frameworks to foster healthier, more resilient cities.

Assessing Buffer Gradient Synergies: Comparing Objective and Subjective Evaluations of Urban Park Ecosystem Services in Century Park, Shanghai

Urban parks provide essential ecosystem services (ESs) that enhance human wellbeing. However, discrepancies often arise between objective assessments of these services and stakeholders’ subjective perceptions. This study addresses a research gap concerning the synergies and tradeoffs between objective evaluations and subjective perceptions of key ecosystem services across various spatial scales. We investigated six key ecosystem services in Century Park, Shanghai, across seven buffer radii (8–100 m). Objective data were obtained from park view images (PVIs) and spatial analysis, while subjective perceptions were gathered through a scoring survey of 33 stakeholders. The key finding is that a buffer radius of 35 m offers optimal synergy between objective and subjective assessments for most ESs, particularly in pollution mediation, temperature regulation, and cultural services. Professionals showed stronger alignment in regulatory services like pollution mediation and temperature regulation, while residents exhibited higher synergy in net primary production (NPP) beyond a 75 m radius. Notably, cultural services displayed nuanced differences, with professionals preferring simpler landscapes and residents demonstrating varied aesthetic preferences. These findings emphasize the importance of integrating objective data and human perceptions in urban green space planning and governance. By incorporating diverse stakeholders and identifying optimal buffer zones, planners and designers can effectively balance ESs with human experiences. This approach ultimately fosters more sustainable and wellbeing-centered urban environments.

Impacts of inequalities in utilization of key maternal health service on fertility preference among high parity women in four selected regions of Ethiopia

BackgroundFertility is one of the three main components which determines the size, structure, and composition of a population, and fertility preferences are important measures for forecasting fertility levels of a population. Therefore, this study aims to assess the impacts of the inequalities in the utilization of key maternal health services on fertility preference among high parity women in four selected regions (i.e., Afar, Beninshangul-Gumuz, Gambella and Somali) of Ethiopia.MethodsThe study used data collected for the 2016 Ethiopian Demographic and Health Surveys (EDHS) survey. It includes a total of 977 high parity women (104 urban and 873 rural) residing in the four regions of the study. Bivariate logistic regression was used to select the potential variables by using a cut off p-value < 0.2 and then the multivariable logistic regression analyses were performed to assess the association between the selected explanatory variables (i.e., control and exposure variables) and the outcome variable (i.e. fertility preference). Further, the study employed a Population Attributable Fractions (PAFs) to examine the population level impacts of the inequalities in maternal and child health service variables on fertility preference.ResultsThe results showed that religion, household wealth index, place of delivery and contraceptive use were significantly associated with fertility preference. The results of the PAFs analysis indicated that contraceptive use had the biggest impact (80%), meaning that non-use of contraceptive increased fertility preference among women in the four regions. Similarly, out of health facility delivery increased fertility preference by 37%.ConclusionThe study findings underscore the critical factors influencing women’s fertility preferences in the studied regions. Low utilization of maternal health services had an impact on fertility preference, accounting for more than half of the observed variations in fertility preferences. To address this issue, targeted interventions are recommended: enhancing access to maternal health services, strengthening fertility control programs, promoting the benefits of using these services, and actively addressing inequalities.

Native bee Pollination Ecosystem Services in Agricultural Wetlands and Riparian Protected Lands

Many freshwater wetlands and riparian systems are protected within agricultural landscapes. Yet, pollinator ecosystem services are seldom considered key ecosystem services provided by these conservation easements. The purpose of this study is to explore the extent of protected aquatic lands to provide pollination ecosystem services by assessing pollinator abundances, crop yield changes, and value estimations of increased soybean yields from a subset of common native solitary bees. We created a novel geodatabase of United States Department of Agriculture (USDA) conservation easements and used this database in the InVEST crop pollination model to model wild solitary bee pollination. We then estimated the monetary value of yield increases provided by pollinators. We found that wetland uplands provided the greatest potential for pollination services for ground nesting bees, followed by herbaceous and forested riparian respectively. Stem nesters preferred forested riparian, then upland habitats. In soybeans fields, we found wild pollinators can provide up to 5.5% yield response from current private aquatic conservation lands. The current landscape is not optimized to use wetlands and riparian conservation lands as pollinator habitat, but these results suggest protected aquatic lands can sustainably increase wild pollination services to agricultural crops if landscapes are managed, protected, and optimized with pollinator services as co-benefit.

Evaluating the Effects of Wetland Restoration on Ecosystem Services Using InVEST and Geostatistics: A Case Study of Dongting Lake in China

Ecological restoration projects aim to recover ecosystems that have been degraded, damaged, or destroyed. The effective assessment of these projects is crucial for ensuring that restoration goals are met and for guiding future efforts. The Poplar Ecological Restoration Project (PERP), focused on removing floodplain poplar plantations, is a key environmental initiative in China to preserve the ecological functions and services of the Dongting Lake freshwater wetland complex. Understanding the dynamic changes in ecosystem services and their trade-offs/synergies before and after the project is crucial for ensuring that ecosystem services are maintained and enhanced. This study selected three key ecosystem services, water conservation, carbon storage, and habitat quality, as indicators to assess the PERP. Using the Integrated Valuation of Ecosystem Services and Trade-offs (InVEST) model and geostatistical methods, including the Spearman correlation analysis and spatial autocorrelation analysis, we explored the ecological outcomes of the project. The results indicated that since its implementation in 2014, the PERP has significantly altered the land use and land cover (LULC) in the lake. Most of the former plantations have been converted into reedbeds (17,404 ha), followed by sedgelands (3841 ha), mudflats (443 ha), shallow waters (382 ha), and deep waters (301 ha). During this period, water conservation and habitat quality initially decreased and then increased, while carbon storage continuously declined. Overall, all assessed services showed an increasing trend except for carbon storage, resulting in a slight decrease in the integrated ecosystem services. Moreover, there were strong bivariate associations among the three investigated ecosystem services, and the synergies were strengthened during the project. Importantly, these synergies became positive after the PERP, meaning that the improvement of one service enhanced others, potentially leading to a more sustainable and resilient ecosystem.

Important Crop Pollinators Respond Less Negatively to Anthropogenic Land Use Than Other Animals.

Animal-mediated pollination is a key ecosystem service required to some extent by almost three-quarters of the leading human food crops in global food production. Anthropogenic pressures such as habitat loss and land-use intensification are causing shifts in ecological community composition, potentially resulting in declines in pollination services and impacting crop production. Previous research has often overlooked interspecific differences in pollination contribution, yet such differences mean that biodiversity declines will not necessarily negatively impact pollination. Here, we use a novel species-level ecosystem service contribution matrix along with mixed-effects models to explore how groups of terrestrial species who contribute differently to crop pollination respond globally to land-use type, land-use intensity, and availability of natural habitats in the surrounding landscape. We find that the species whose contribution to crop pollination is higher generally respond less negatively (and in some cases positively) to human disturbance of land, compared to species that contribute less or not at all to pollination. This result may be due to these high-contribution species being less sensitive to anthropogenic land conversions, which has led humans to being more reliant on them for crop pollination. However, it also suggests that there is potential for crop pollination to be resilient in the face of anthropogenic land conversions. With such a high proportion of food crops requiring animal-mediated pollination to some extent, understanding how anthropogenic landscapes impact ecological communities and the consequences for pollination is critical for ensuring food security.

Inequalities in local funding cuts to environmental and regulatory service expenditure in England

Abstract Background The financial crisis in 2008 has led to governments across Europe introducing austerity measures. England has experienced significant financial cuts to local authority (LA) services. Environmental and regulatory (ER) services provide key functions in public protection such as, Food Safety (FS) and Animal and Public Health Infectious Disease Control (APH), services which are key infectious disease resilience. Here we investigate inequalities in local funding cuts to ER services by socioeconomic deprivation, LA type, and urbanicity, and impact on key ER service indicators. Methods This ecological study uses longitudinal modelling techniques to analyse trends in ER expenditure since the introduction of austerity and the inequalities present. We use Generalised Estimating Equations to estimate the annual percent change of ER service expenditure, and FS and APH expenditure between 2009/10 and 2020/21 in relation to deprivation, LA type and population density. Quasi-Poisson regression is used to assess impact of cuts on ER service indicators. Results Areas of higher deprivation had the largest reduction in expenditure, with ER and FS and APH cuts of 2% and of 23% respectively, compared to a 1% and 8% reduction in the least deprived areas. The share of ER expenditure spent on FS and APH decreased by 13% in the most deprived authorities compared to 6% in the least deprived areas. London boroughs had the greatest reductions in FS and APH expenditure, decreasing by 10%. Both ER and FS and APH expenditure decreased with increasing population density. Preliminary analysis shows inequalities in food business hygiene ratings in addition to other key ER service indicators since the introduction of these cuts. Conclusions The unequal distribution of cuts shows the need for increased and equitable investment into these services to enable resilience to infectious disease threats, and to prevent widening of health inequalities. Key messages • This work provides strong evidence of inequalities in local funding cuts to ER services and highlights where investment should be focused, in order to protect environmental and public health. • This work introduces the impact of local funding cuts on a vital public health service and lays the foundation for future work into the unequal impact of cuts to these services on health outcomes.

Advancing Pharmaceutical Care in Community Pharmacies in Poland: A Blueprint for Enhanced Patient Care Quality.

Background: This article reviews the current state of pharmaceutical care in community pharmacies in Poland and proposes a collaborative framework for its advancement. While pharmaceutical care has evolved significantly worldwide, with Europe leading the way, Poland has lagged in its development. Although Polish pharmacists are well-qualified and community pharmacies are numerous, pharmaceutical care remains underdeveloped. Methods: We conducted a literature review and analyzed case studies from European countries with advanced pharmaceutical services. Based on these findings, we collaborated with policy makers, commissioners, and academics to develop a framework for enhancing pharmaceutical care in Poland. The plan emphasizes integrating seven key services into Polish community pharmacies. Results: Our proposed framework outlines seven essential pharmaceutical services: medicine use reviews, new medicine services, minor ailment services, repeat prescription services, integrated prevention programs, cardiovascular disease prevention programs, and vaccination programs. Evidence from other European countries suggests that implementing these services could significantly improve health outcomes and patient quality of life. This is particularly important in light of Poland's ageing population, the rising prevalence of chronic diseases, and the healthcare system's increasing burden due to polypharmacy. Conclusions: The proposed framework presents a practical and collaborative approach to advancing pharmaceutical care in Poland. By adopting these key services, community pharmacies could play a more integral role in improving patient care quality and alleviating pressure on the broader healthcare system.

Assessing the economic and nutritional value of pollination services in Nepal

Pollination is a key ecosystem service crucial for supporting agricultural production, economic growth, social inclusion, and environmental protection. Understanding the economic value of pollination and its impact on human health and nutrition is essential for effective pollinator conservation and management. This study evaluates the economic and nutritional value of pollination services in Nepal and quantifies historic changes in pollinator reliance. Using public data on agricultural production and commodity prices, in combination with published nutritional composition values, we employ the dependency-ratio method to quantify economic and nutritional value across different regions of the country and through time. We conservatively estimate the annual economic value of pollination services in Nepal at US $477 million, representing 9% of total agricultural revenue. Pollinator-dependent crops, particularly fruits and vegetables are the source of essential nutrients; 40% of plant-based vitamin A and 14% of vitamin C are directly attributable to insect pollination. The cultivated area of these pollinator-dependent crops has increased by 91% in Nepal over 20 years – 3.7 times faster than equivalent increases in non-pollinator-dependent crops. The decline in wild pollinators during the same time period poses a threat, leading to potential pollination deficits and crop losses. Our study underscores the importance of conserving and managing pollinators to ensure sustainable agriculture, food security, and nutrition. Targeted efforts, including policy interventions and conservation strategies, are needed to safeguard pollinator populations and enhance pollination services.

Do You Like Online Shopping? A Case Study Courier Service Quality and Customer Satisfaction Between Malaysia, Indonesia, and India

The surge in online shopping has led to a growing demand for courier services, making it crucial to understand how service quality impacts customer satisfaction. This study aims to evaluate the effect of five key service quality dimensions—tangibility, reliability, responsiveness, assurance, and empathy—on customer satisfaction in the courier industry across Malaysia, India, and Indonesia. An online survey was conducted with 150 respondents from Universiti Sains Malaysia (USM), Universitas Brawijaya, Indonesia, CMS Business School, India, and IMS Engineering School, India. Regression analysis revealed that only empathy had a significant positive relationship with customer satisfaction, while tangibility, reliability, responsiveness, and assurance did not show significant impacts. These findings suggest that courier companies should focus on improving empathy in their customer service interactions to enhance satisfaction. Understanding and addressing customer needs through personalized service can lead to higher satisfaction and loyalty. This study contributes to the literature on service quality in the courier industry, particularly in the context of online shopping across multiple countries

Terrestrial land use signals on groundwater fauna beyond current protection buffers.

Terrestrial and aquatic ecosystems are tightly linked, with direct implications for applied resource management and conservation. It is well known that human land use change and intensification of terrestrial systems can have large impacts on surface freshwater ecosystems. Contrastingly, the study and understanding of such land use impacts on groundwater communities is lagging behind. Both the impact strength of land use on groundwater communities and the spatial extents at which such interlinkages are operating are largely unknown, despite our reliance on groundwater for drinking water extraction as a key ecosystem service. Here, we analyzed groundwater amphipod occurrence from several hundred shallow groundwater aquifers used for drinking water extraction across a region of varying agricultural intensity and human population density in Switzerland. Despite drinking water extraction sites being generally built at locations with expected minimal aboveground impacts on water quality, we found a direct correlation between land use type and intensity within the surrounding catchment area and the locally measured nitrate concentrations, which is a direct proxy for drinking water quality. Furthermore, groundwater amphipods were more likely to be found at sites with higher forest coverage than at sites with higher crop and intensive pasture coverages, clearly indicating a tight connection between aboveground land use and groundwater biodiversity. Our results indicate that land use type effects on groundwater communities are most relevant and pronounced to spatial scales of about 400-1000 m around the groundwater sampling site. Importantly, the here identified spatial scale is 1.2- to 3-fold exceeding the average extent of currently defined groundwater protection zones. We postulate that incorporating an ecosystem perspective into groundwater management strategies is needed for effective protection of groundwater quality and biodiversity.

Navigating integration challenges: Insights from migrant dairy farm workers in New Zealand

As the global demand for milk products continues to increase and dairy sectors become more concentrated, a pressing question arises: who will milk the cows and where will they come from? Mirroring global trends, the New Zealand dairy industry has experienced significant structural changes, with a shift from family-run dairy farms to larger commercially orientated operations. At the same time, domestic socio-economic and demographic changes have resulted in rural to urban migration. These factors have contributed to a shortage of skilled labour in some regions. To meet its labour demands, the New Zealand dairy sector has relied increasingly heavily on temporary migrant workers, who face significant challenges integrating into their new communities. This study uses data from in-depth interviews with 25 migrant dairy farm workers in Canterbury, New Zealand, and a modified conceptual framework for integration developed by Ager and Strang to enhance our understanding of how skilled migrants in the dairy sector adapt to unfamiliar host communities. Through thematic analysis we identify the factors that either facilitate or hinder the successful integration of this important but vulnerable group. Key themes include motivations for moving to New Zealand, pathways to obtaining their positions, and the primary challenges that they experience in attempting to integrate. Challenges include physical and social isolation, discrimination, and a lack of access to key services. As the agricultural sector continues to grow, it is essential to provide migrant farm workers with adequate support to ensure their successful social, cultural, and economic integration.

Exploring Smart Airports’ Information Service Technology for Sustainability: Integration of the Delphi and Kano Approaches

Airport digitalization has revolutionized service delivery at passenger touchpoints, which leads to sustainable passenger loyalty. However, it is critical to determine whether this rapid transition to digital services genuinely enhances passenger satisfaction with airport services. This study uses a mixed-method approach to identify key traditional and technology-driven information services in smart airports. The specific aim is to determine the optimal balance in which digital technologies can effectively replace human-provided services to establish sustainable passenger loyalty. Two rounds of Delphi surveys were conducted with panels of 23 and 21 experts, followed by an online Kano survey with 401 international passengers. The Delphi analysis identified 16 key information service attributes, while the Kano analysis revealed that the majority of technology-based services were attractive and positively influenced passenger satisfaction. By contrast, human-based services were mostly indifferent, although some were vital for boosting satisfaction and preventing dissatisfaction. These results advance the current airport service research and provide practical insights into optimizing passenger experiences through the strategic integration of technology for sustainable smart airports while maintaining essential human-provided services.

The responses of ecosystem services in coastal cities to urbanization in 30 years: A case study of Qingdao City, China

Coastal urban areas play a pivotal role in regional economic growth, yet they are also sensitive regions where the natural environment interacts with human activities. Rapid urbanization has led to ecological issues, such as the degradation of key ecosystem services (ESs) in coastal cities. Understanding the impact of urbanization on the supply and demand of ESs in coastal cities is crucial for ensuring the healthy and sustainable development of the socio-economy in these areas. This study takes the coastal city of Qingdao as a case study, with a focus on the supply and demand relationships of seven key ESs—carbon sequestration, food production, habitat quality, recreational capacity, soil retention, water yield and marine aquaculture—as well as their responses to population growth, economic development, and spatial expansion, which are three distinct aspects of urbanization. The findings indicate that: (I) From 1992 to 2022, the evolution of different ESs exhibited variability, all displaying notable spatial imbalances. (II) During this period, the urbanization process in Qingdao had a pronounced negative effect on the supply and demand of ESs. Spatial urbanization had the most significant impact on carbon sequestration, food production, habitat quality, water yield, and marine aquaculture, while population urbanization most notably affected recreational capacity. (III) The sensitivity of different types of ESs to population, economic, and spatial urbanization varies. Carbon sequestration, food production, recreational capacity, soil retention, water yield, and marine aquaculture were most sensitive to economic urbanization, whereas habitat quality was most sensitive to spatial urbanization. This research provides a basis for decision-making in the sustainable development and comprehensive management of coastal cities and their ecosystems.
